Energy disposal in the dissociative charge transfer reaction He ++N 2O→N 2+(X, ν″)+O+He and collisional quenching of N 2+(X, ν″) by N 2O

Abstract

The charge transfer reaction of He + with N 2O produces vibrationally excited N 2 + (X) ions. The relaxation processes occurring after formation of the N 2 + (X, ν″) ions have been investigated. Charge transfer with N 2O is the main relaxation mechanism and its rate does not vary much with the internal energy of N 2 +. Analysis of the energy disposal in the He +/N 2O charge transfer indicate that multiple excitation states of N 2O, nearly resonant with the recombination energy of He + are most certainly implied in the charge transfer.
